There has been a growing movement to regulate carbon dioxide emissions. Therefore, saving fossil fuel consumption is an issue, and there is a strong demand for vehicles that are lighter and have improved fuel efficiency.
The tire, which is one of the vehicle parts, is not an example. In particular, it is important to reduce the unsprung weight by reducing the weight of tires because it leads to a reduction in the vehicle frame.

As a conventional weight reduction method, we have been researching weight reduction for each part, but since there are no parts that have such a wasteful volume from the beginning, we decided to use a new material with a large weight specific strength or weight specific rigidity. The main research is to reduce the weight by using it, and some have been found to have good performance. However, such new materials are generally expensive, and in the case of pneumatic radial tires, most expensive materials cannot be put to practical use in terms of cost because of their low unit price. Therefore, it has come to be expected that one component has two or more functions.

A rubber composition containing rubber is used. Thus, in the present invention, the epoxidized natural rubber is used as the carcass-covered rubber.
Since the rubber composition containing (ENR) is used, the epoxidized natural rubber has good air permeation resistance, so that the carcass layer can also serve as an inner liner.

FIG. 1 is a meridional direction half-section explanatory view of an example of a pneumatic radial tire of the present invention. In FIG. 1, a carcass layer composed of a carcass cord 2 and a carcass covering rubber 4 is mounted between a pair of left and right bead portions 1, 1. The end of the carcass layer is folded around the bead core 3 from the inside of the tire to the outside and wound up. This carcass layer is formed by embedding an organic fiber cord such as a nylon fiber cord, a polyester fiber cord, an aromatic polyamide fiber cord or the like, or a metal cord such as a steel cord into a coat rubber (carcass covering rubber) to form a sheet.

とすることができる。Since epoxidized natural rubber is excellent in wet performance and on-ice performance, it has been used as a rubber composition for a tread as disclosed in JP-A-3-126737. However, since it is slightly inferior in air permeation resistance to isoprene isobutylene rubber (butyl rubber), it is not used for the inner liner 5 provided on the inner surface of the tire in order to suppress air permeation. In the present invention, the carcass layer is considerably thicker than the inner liner 5,
Keeping in mind that even if the air permeation resistance is slightly inferior, it is possible to cover with that thickness, and it was decided to use epoxidized natural rubber as a liner material for the inner liner 5 as a carcass material for the carcass layer. As a result of research, since epoxidized natural rubber has good adhesion to fiber cords, there is no particular problem in using it as a carcass material, and its air permeation resistance is much better than that of a carcass-coated rubber that is generally used as a carcass material. Therefore, it has been found that the function of the carcass material and the function of the liner material can be provided at the same time, and the carcass material is made of epoxidized natural rubber. This can eliminate the need for the inner liner 5.

化率が大きくなると明らかに耐空気透過性が向上する。Epoxidation ratio of epoxidized natural rubber is 5%
That is all. Epoxidation of natural rubber introduces an epoxy group into a double bond in the rubber, and the epoxidation rate means a ratio of epoxidized to all double bonds of natural rubber. Figure 2 shows the index of air permeability (air permeation resistance) when the epoxidation rate of natural rubber is changed (epoxidation rate 0%
Is set to 100). As shown in FIG. 2, the air permeation resistance is obviously improved as the epoxidation rate is increased.

よい。The air permeation resistance becomes lower as the carcass layer becomes thicker and the material having lower air permeation resistance is used.
In this case, the higher the epoxidation rate of the epoxidized natural rubber is, or the larger the compounding amount of the epoxidized natural rubber is, the lower the air permeation resistance of the carcass material becomes. The air permeation resistance required for tires differs depending on the application and type of tire, so it is a case-by-case how much epoxidized natural rubber should be used, but the epoxidation ratio is less than 5%. In the case of, there is no effect on the air permeation resistance. Further, when the epoxidation rate exceeds 70%, it becomes plastic-like, and it becomes difficult to mix when processing by Banbury mixing. Therefore, it is preferably 70% or less.

Also regarding this blending amount, the required blending amount also differs because the air permeation resistance required depends on the application and type of the tire, but if it is less than 5% by weight, there is no effect. However, since epoxidized natural rubber has good adhesiveness to the carcass fiber cord, there is no particular problem even if it is 100% by weight. Polymers that can be used simultaneously with the epoxidized natural rubber include, but are not limited to, natural rubber,

然ゴムのエポキシ化率と配合量を決定するのがよい。FIG. 3 is an index of air permeability (air permeability resistance) when the epoxidized natural rubber having an epoxidation rate of 50% is replaced with the polymer component in the carcass-coated rubber (rubber composition A in Table 1). (100 when the compounding amount is 0% by weight) is shown. As shown in FIG. 3, the air permeation resistance is obviously improved as the compounding amount of the epoxidized natural rubber is increased. As shown in FIG. 2, as the epoxidation rate of natural rubber is increased, the air permeability decreases in a quadratic curve. On the other hand, looking at FIG. 3,
When the compounding amount of epoxidized natural rubber is increased, the air permeability decreases almost linearly. In other words, when the epoxidation ratio with respect to the amount of double bonds in the rubber composition constituting the carcass-covered rubber is the same, it is necessary to blend a small amount of epoxidized natural rubber having a high epoxidation ratio in terms of air permeation resistance. Therefore, it can be said that it is advantageous. However, as mentioned above, since epoxidized natural rubber with a high epoxidation rate does not have good processability, in addition to air permeation resistance, in terms of processability, the epoxidation rate and compounding amount of epoxidized natural rubber It is better to decide.
